AUTOMATIC WATER CIRCULAT'OR FOBr INTERNAL COMBUSTION ENGINES Application filed June '16,

This invention relates to means for causing the circulation of water in the water jacket of an internal combustion engine, and more particularly to means of this character in which the circulation is caused by the eX- plosion of gases withinthecylinder itself actingto force water positively out of the water jacket and admit cool water thereto as illustrated in my prior Patents No. 1,743,- 971 and 1,655,374.

A further object or" the invention is to provide improved means for absorbing the heat from the exhaust gases.

ther objec s will appear in the course of c following description.

invention is illustrated in the accoinpairing drawings, wherein Fig. 1 is an elevaticn of a water circulatinechanisni constructed in accordance with my invention, the cylinder .and water jacket of the engine being shown in section;

2 is a vertical sectional view through the water jacket of the check valve and through the check valve casing;

Fig. 3 is a fragmentary section through the firing head of the engine showing the gas outle pipe leading therefrom in section.

Referring to these drawings, designates the cylinder of any ordinary internal corn bustion en ine and 11 the water jacket thereof.

The firing head. of the cylinder is designat ed 12, while the corresponding head of the water jacket is designated 13. Entering the water jacket more or less adjacent the head 13 is a supply pipe 14 which connects to the lower end of a water supply tank 15 or other suitable source of supply and which carries the globe valve 16. Extending from the water jacket 11 preferably opposite to the pipe 1% is the outlet pipe 1'? which discharges downward into the upper end of the tank 15. Disposed outward of the head 13 is a casing or water jacket 18. This water jacket has an inlet pipe 19 which connects by in'eans'ot a coupling 20 to a nipple 21 extending from the inlet water pipe 14. The outlet pipe from the water acket 18 is designated 22 and is ronnected by a coupling 23 to a nipple pro ecting from the pipe 17. Disposed within the 1930. Serial No. 460.252.

jacket 18 is a casing of a check valve. The casing is made in two sections 24; and 25. The lower section of the casing is formed with a longitudinally extending bore 26 and the upper end of the lower section is formed with a valve seat 27 into which this bore opens. The upper end of the upper section is reduced in diameter and screw-threaded as at 28 for engagement with the enlarged screwthreaded lower end 29 or" the upper section of the valve casing. This upper section has a bore extending entirely through it. he threaded portion 28 01" the lower section has screw-threaded engagement with the enlarged portion 29 of the upper section and also has screw-t ireaded engagement at 30 with the jacket 18. The lower section has a many-sided head 31 whereby the lower section may be screwed firmly into the lower screw-threaded end of the water jacket 1 Gperating'within the bore 26 and coacting with the seat 27 is the check valve 32 which may have any usual or ordinary form and which is held to its seat by a spring 33 bearing against a plate 34 in turn supported by a shoulder 35 within the upper section 25 of the check valve casing. This plate 34 is apertured at 36. The spring 33 bears against the plate 34 and urges the check valve 32 to its seat. passes through a stufiing box and gland 37 which engages the upper end or" the jacket 18. The upper end or" the section 25 is engaged by a coupling 38 to a pipe 39 which in turn is engaged by a coupling 40 with a pipe l1 which extends downward and discharges through the wall of the water jacket 11 at a point remote from the head 13. This pipe a1 is provided with a drain valve 42. The pipe 19 is also provided with a globe valve 43 and the lower end or" the pipe M is connected to a T 1 having a drain plug 14*. Thus all parts of the water jacket may be drained to eliminate any possible freezing.

Extending up into the lower section 24 of the water jacket and having gas-tight engagement therewith is a pipe 44 which extends through the head 13 of the water jacket 11 and opens through the head 12 of the cylinder. This nipple 4A has at its extremity a very The upper end of the section 25 small opening 45. This permits a very slight amount of gas under compression caused by the explosion within the cylinder to pass out from the cylinder up past the check valve 32 and be discharged by the pipes 34 and 41 into the interior of the water jacket-11.

It will be seen that at each explosion of the engine, a portion of the heated gases from the cylinder'enters the lower section of the check valve casing 24 and raises the check valve so that the gases from the explosion pass directly through the upper section of the check valve casing and on up through pipe 39 and down to the lower portion of the water jacket 11.

This will cause the water to circulate around the cylinder in the engine and cool the cylinder an d this water is then forced out throughthe pipe 17 to the tank 15 or other source of water supply. I have found in practice that this circulation is steady, continuous and automatic with each explosion of the engine. lVhile I have illustrated certain details of construction and arrangements of parts, I do not wish to be limited thereto as obviously these might be changed without departingfrom the spirit of the invention as defined in the appended claims.

, I claim I 1. The-combination with the cylinder of an internal combustion engine, a water jacket therefor, a supply pipe, a discharge pipe and a tank fromwhich the, supply tank takes wa .ter and into which the discharge pipe discharges water, means for causing a circulation of water within the water jacket upon each explosion of the engine including a check valve casing, a pipe leading into the check valve casing from the firing head of the engine, the pipe having a very small inlet aperture, a pipe leading from the opposite end of the valve casing into the water jacket, a water jacket surrounding the valve casing, and meansfor causing the circulation of cooling water through said water jacket.

2. The combination with a cylinder of an internal combustion engine, a water jacket therefor, a supply pipe and an inlet pipe and a tank, into which the supply pipe and inlet pipelead, of means for causing a circulation of water within the water jacket upon eachexplosion of the engine including a check valve casing formed in two sections having screw-threaded engagement with each other,

a checkvalve disposed within said sections and urged to its seat, the lower section of the casing being connected through the firing head of thecylinder by a member having a very small inlet aperture, the opposite end of the valve casing being connected to the interior of the water jacket, a water jacket enclosingthe valve casing, the water j acket,

having a pipe connection at its lower end to the supply pipe of the cylinder water jacket and at its upper end having a pipe connection to the discharge pipe of the water jacket.

3. The combination with a water jacketed internal combustion engine and means for ing and inlet and outlet connections to the water jacket; I

4. The combination with a water jacketed internal combustion engine,of a supply pipe entering the Water jacket and a discharge pipe extendingtherefrom, a check valve casing connected at one end to'the interior of' the engine cylinder, at the firing head thereof, the other end of the check valve casing communicating with the interior of the water jacket remotefrom the firing head, a water jacket enclosing the check valve casing and having an inlet connection leading from the pipe supplying water to the jacket, and an outlet connection leading into the discharge pipe from the jacket, the inlet connection being provided with a cut-off valve.

5. In means for automatically circulating the water through a jacket ofan internal combustion engine, a check valve casing formed in two sections, each section havin a longitudinally extending bore, one end 0 one section being reduced in diameter and screw-threaded, the adjacent end of the other section being internally screw-threaded to receive the screw-threaded end of the first named section, the first named section at the screw-threaded end being formed with a check valve seat, a check valve disposed on threaded and having a head, and a water jacket screw-threaded at one end for engagement with the last named screw-threads and a packing gland having screw-threaded engagement with the opposite end of the water j acket'and surrounding the body of the second named section, the water jacket having an inlet aperture and an outlet aperture.

In testimony whereof I hereunto aflix my signature. I
